AN-417: Fast Rail-to-Rail Operational Amplifiers Ease Design Constraints in Low Voltage High Speed Systems (pdf, 228 kB)
Movement towards lower power supply voltages is driven by the demand that systems consume less and less power coupled with the desire to reduce the number of power supply voltages in the system. The following applications are discussed: Single-Ended and Differential Input ADC Input Circuits, Video Line Driver, Active Filter, HDSL Transceiver, and Transformer Drive Circuits.
AN-414: Low Cost, Low Power Devices for HDSL Applications (pdf, 41 kB)
AN-402: Replacing Output Clamping Op Amps with Input Clamping Amps (pdf, 55 kB)
So far most clamping amplifiers have relied upon an output clamping architecture and are called output clamp amps (OCAs). A new architecture called an input clamp amp (ICA) offers superior clamping accuracy and lower distortion.

ADIsim Design/Simulation Tools (1)

ADIsimOpAmp™
This tool will help with the selection, evaluation and troubleshooting of voltage feedback Op-Amps. It uses typical data to model the behavior of a selected amplifier. It allows a user to select an amplifier, configure a circuit, apply a signal and evaluate the performance. It is useful for checking an amplifier's spec's such as Bandwidth, Slew Rate, Input/Output Range, Gain Error, Load Current, Stability Issues and DC Errors in a given circuit.

OpAmp Stability
An applet for demonstrating stability effects in opamp buffers.
Voltage Reference Wizard (downloadable)
This Wizard helps you select the most suitable voltage for a use with a data converter. Supply the Wizard with a given data converter; it will provide you with a number of suitable references plus the maximum DC error contributed to your overall system. Or enter the amount of DC error your system can tolerate and find out which of ADI’s reference and data converter pairs will meet your requirement.
